Motivation:
Documentation was added in #2401 to aid developers in understanding
how HttpObjectAggregator works and that it needs an encoder before it.
In #2471 it was pointed out that the documentation added can actually
add to the confusion and that it might have a typo.
This is an attempt at clearing up that confusion. Feedback is welcome.
Modifications:
- Adjust class level javadoc for HttpObjectAggregator
* Remove reference to HttpRequestEncoder
* Point out when HttpResponseEncoder is needed
* Point out that either HttpRequestDecoder or HttpResponseDecoder is needed
* Make clear everything must be added before HttpObjectAggregator
* Mention HttpServerCodec
Result:
Avoid confusion about dependencies for HttpObjectAggregator on the pipeline.
